I was watching a PBS special called Appalachia and in the first episode, there was a reference to trading routes between the Indians of the Upper Midwest and those of ffice:smarttags” />Appalachia. Unfortunately, I was not recording so the exact phrasing escapes me now. Did anyone else catch this? If trading occurred before Wasicu arrived, it could have some significance to the “Blackfeet Connection”, language commonality, etc. I hope the series re-airs so I can see if they list any sources that I could access. Maybe someone here has something.
